With their compact, stunning, piano -like finished cabinets, the HRS Series subs make a design statement about themselves – and you. What’s more, beneath this beautiful exterior lies some of today’s most advanced audio science. Like Sunfire’s High Back-emf driver technology that produces massive amounts of low distortion bass from some of the smallest drivers around. In fact, the HRS-12 delivers output equal to the performance of most available 15” subwoofers and does so with an unmatched visual finesse. The HRS-12 is ideal for larger rooms and dedicated home theater environments where the emphasis is on movies.
